Using templated method, sulfonic functionalized three dimensional ordered macroporous (3DOM) SiO2-SO3H hybrid materials have been first prepared via in situ transformation of mixed sol com- posed of tetraethoxysilane (TEOS) and (3-mercaptopropyl)trimethoxysilane (MPTMS) infiltrated in the in- terstitial voids of polystyrene colloidal crystal, and followed extraction of template and oxidation of thiol groups to sulfonic groups with H2O2. Samples were characterized by SEM, EDS, FT-IR methods. The re- sults showed...

Using templated method, sulfonic functionalized three dimensional ordered macroporous (3DOM) SiO2-SO3H hybrid materials have been first prepared via in situ transformation of mixed sol com- posed of tetraethoxysilane (TEOS) and (3-mercaptopropyl)trimethoxysilane (MPTMS) infiltrated in the in- terstitial voids of polystyrene colloidal crystal, and followed extraction of template and oxidation of thiol groups to sulfonic groups with H2O2. Samples were characterized by SEM, EDS, FT-IR methods. The re- sults showed that synthesized materials possessed well 3DOM structure. The pores were about 250 nm and interconnected by small channels of 80 nm. Sulfonic acid groups had been well anchored into structure-wall. The determination of pyridine adsorption of samples revealed that materials have a typic characterization of proton acid, and the proton acid centers increased with the increase of S content. Catalysts showed good performance in esterification of acetic acid with n-butanol, moreover, the higher content of sulfonic acid is, the more active catalysts are. This study provided significant results for development of new high perform- ance solid acid catalysts.

采用模板法,用正硅酸乙酯和3-巯丙基-三甲氧基硅烷的混合溶胶,在聚苯乙烯胶晶间隙中原位转化,除去模板后用双氧水将巯基氧化成磺酸基,首次成功地制备了大孔规整排列的3DOMSiO2-SO3H材料.样品用SEM,EDS,FT-IR等方法进行了测试表征.结果表明,所得到材料的三维大孔结构规整性十分好,大孔孔径大约250nm,并由大约80nm的小孔相连;磺酸基很好地嵌入孔壁基质中,吡啶吸附测定显示了典型的质子酸特征,而且酸中心随硫含量增加而增多.对乙酸与正丁醇的酯化反应显示了良好的催化性能,磺酸含量越大,催化活性越高.这一研究为开发新型高效的固体酸催化剂提供了很有意义的结果.

A powder-A1 plate sandwich rolling processing is proposed for preparation of aluminum alloy foam sandwich with a metallurgy bonding interface.Two methods of heat treatment of foaming agent and addition of Mg were adopted in order to improve the foam stabilization.It was found that foam stability was only improved when heat treatment of TiH_2 and addition of Mg was employed at the same time.The fundamental stabilization mechanism for foaming is investigated.Enhanced wetting,due to addition of Mg,enables the oxidation...

A powder-A1 plate sandwich rolling processing is proposed for preparation of aluminum alloy foam sandwich with a metallurgy bonding interface.Two methods of heat treatment of foaming agent and addition of Mg were adopted in order to improve the foam stabilization.It was found that foam stability was only improved when heat treatment of TiH_2 and addition of Mg was employed at the same time.The fundamental stabilization mechanism for foaming is investigated.Enhanced wetting,due to addition of Mg,enables the oxidation parti- cles created in the production process of the Al-Si alloy powder to be embedded in the cell wall,preventing drainage of liquid metal,making them more effective at foam stabilization.

通过粉末-铝板复合轧制方法制备出一种界面为冶金结合的泡沫铝夹芯板。分别采用对发泡剂的处理和添加Mg元素的方法来提高芯材泡沫的稳定性。研究发现只有同时对发泡剂处理以及添加Mg元素才能够提高泡沫的稳定性。研究了此种方法中重要的泡沫稳定机制,Mg元素的添加改善了铝硅合金粉末原料生产过程中产生的氧化物颗粒在孔壁上的润湿性,使氧化物颗粒嵌入孔壁中,阻碍了孔壁上金属排液现象的产生,有效的起到稳定泡孔的作用。
